Tri cut radial designed with 4 zones of orientation. The 2 central intermediate zones, allow a reorientation of the right of the wire of roving in the principal direction of the efforts. That results in a great stability of form.

This cut, general-purpose of 90° with 160° of apparent wind thanks to the possible adjustment by the tack, is appropriate for the boats of more than 45 '. She is proposed in option with a decreasing grammage for a profit of weight and a greater versatility.
